Exam 1 for NU560 Questions With Complete Solutions
2 types of cellular death Correct Answer apoptosis and
necrosis
3 Components of a cell Correct Answer plasma membrane,
intracellular organelles, cytoplasm
5 types of necrosis Correct Answer Coagulative
Liquefactive
Caseous
Fat
Gangrenous
A nurse knows that active transport requires Correct Answer
receptors capable of recognizing and binding with specific
molecules
A nurse recalls depolarization occurs when the Correct Answer
voltage regulated channels open and the Na+ enter the cell
Actin Correct Answer bundles of long rods near the end of the
cell, break easily, slightly thinner than intermediate, made of 2
chains of the protein actin, most brittle but most versatile, form
web like networks
Action potential Correct Answer depolarization, threshold
potential, repolarization, refractory period, hypo polarization
and hyperpolarization
,active transport Correct Answer Energy-requiring process that
moves material across a cell membrane against a concentration
difference
Example: Na-K+ pump (Acid Reflux)
Aging degenerative extracellular changes Correct Answer
collagen binding and cross-linking, increase in free radicals'
effects on cells, structural alteration, peripheral vascular disease
and oxidative stress
Alcohol Correct Answer metabolized via the microsomal p-
450
Alcohol-induced liver disease Correct Answer Fatty liver
disease
Alcoholic hepatitis
Cirrhosis
Anabolism Correct Answer energy using (upward)
Anaphase Correct Answer Phase of mitosis in which the
chromosomes separate and move to opposite ends of the cell
Antibiotics (some work) Correct Answer by shutting down
the ribosomes in bacteria
Apoptosis Correct Answer cell contains remain intake and no
adjacent inflammation
Apoptosis Correct Answer is a process of programmed cell
death, ER stress results in apoptotic cell death. is the active
, process of cellular destruction, can occur normally or
pathologically
Apoptosis Correct Answer no inflammatory changes, Type 1-
programmed cell death, Type II- autophagic cell death
Atrophy Correct Answer decrease in cell size
Atrophy example Correct Answer -renal atrophy secondary to
atherosclerosis
-thinning of skin w/ age
-cortical atrophy w/ dementia (narrowed gyri)
-disuse atrophy of muscles (fat replaces muscle fibers)
autocrine signaling Correct Answer cells respond to signaling
substances that they themselves secrete, cell that signals its self,
involved in cancer thought to play a key role in metastasis
Autophagy Correct Answer recycling center, development,
cell proliferation, remodeling, neuro-degeneration, tumor
suppression, regulation of the life span, and cell death
Axons Correct Answer conduct impulses away from the cell
body
Basement membranes, Correct Answer thin, tough, flexible,
lies beneath epithelial cells, surrounds individual cells (muscle,
fat, schwann)
